Specification formiug part of Letters Patent N0. 220,514, dated October 14, 1879; application filod August 13, 1878.

T0 all whom lt mag; concem Be it known that; we, HARRISON W001)- MANSE and SAMUEL LEBKIOKER, of Freeport, Stephenson count-y, State of Illinois, hzwe inventd new and usfu1 Improvements in Windmills, of which tl1e following is a ful1 deseription, reference being had to the accompanying drawings, in which Figure 1 is a side elevation; Fig. 2, a top view; Fig. 3, a. detail; Fig. 4, a side elevation, showing the side opposite t0 that represened in Eig. l; Fig. 5 a vertical seetion of the parts shown; Fig. 6, a plan view 0f the par ts represented.

'lhis invention consists, first, in providing a 1ever in connection with a brake-wheel, so arranged as t0 be operated by a projection upon the inner end 01" the vane, for the purpose of renderiug the bmke 11101e eflicient; in the peculiar construction and. arrangement of the main casting and bed-plate, supporting balls, so as to decrease the friction; and in the peeuliar arrangement 0f ehe levers and weight, in conneetiou Wit-h the vane am]. ma'in frame, for the purpose of automatically ad justing the position 0f the wind-wheel as required by ohe varying f0rce 0f ehe wind.

In the dra-wings, A represents the main casting, the lower end, A, of which forms a shaft. Bis the main plante, secured to the top of the frame, through an opening in which the sha-ft; A passes. 0 is a hinged vane.

The wind-wheel is not shown, but is permanently secured to a shaffi, D, which rotates in a bearing, E, eouneeted with the main casting. On the inner end. 0f this shaft D is a pitmanwheel, a.

b is a brakesho arranged to engage with the whee1 a. I1; is secured to a lever, c, which is pivoted a1: d t0 {ehe main casting.

e is a projection upon the vane-head, arranged to engage with the free end of the levr c when thewheel is' Gut of the Wind. f is a st0p t0 c0me in eontact with some part of the main casting, to limit the movemenl: 0f the same. g are balls, whieh rest upou the plate B, which is provided with a, shoulder, h. 'i is a eap, connected wibh the ma-in cast-ing als the top of the shaft: A, and which rests upon the balls 9-.

'.I.he shaft A is somewhat smaller tha11 the opening in the plate B, through whichit Passes, and the balls g are of such size that the shaft in its rotation comes in contact With them instead. of with the surface 0f the opening in the p1ate B, so that the eap and the shaft A do not either 0f them come in contact with any fixed part, bat both eome in contaet With the balls g. A nun1ber 0f these balls sufficient 130 nearly fill the entire spaee within the ledge h are used, as shown in Fig. 6. By this arrangement there will be less friction than when the eonstruction is such that the cap z only rests upon the balls, the shaft eoming in contact with the plate through which it passes.

F is a rod. II; is pivoted a1: its upper end t0 the main casting. G is another rod, the

upper end of whieh is pivoted 1:0 the vane, and

upon its lower end is a weight, H. These two rodsF G am loosely connected together atj. These two rods and the weight are arranged in the usual manner, excep't that it is austomary t0 place the weight upon the 10d F. By placing the weight upon the rod. G, as shown, tl1e efl'ect produeed is mach better than with the old arrangement, as by attaehing tl1e weight to the extended a-rm G 0f the vane it acts wich a leverage as well as by gravity, und moves in a longer am, thus making its action quieker and more delicately uniform.

When the parts are in the position showu in the drawiugs the wind-wheel will be held faein g the wind when it is light. As the force of the Wind increases it will ca1ry the windwheel out 0f Lhe wind partly, a1: the same time raising the rod F, and with it the weighted rod G and as this weighted 10d rises the distance 0f the weight fromm the vane Will coustantly inerease, requiring an increased force to carry the whee1 out 0f the wind. As the force of the wind decreases, the weight will return the wheel t0 its former position. By means of the cord I the whee1 can be thrown out of the Wind, and held as usual.

We are aware that a brake has been applied t0 a windmill. Such a brake is shown in the patent to Anderson, issued 1:0 one of these applicants (WOODMANSE.) Wo therefore (10 n0t; elaim, broa-dly, a brake.

We are also aware that a weight 0f varying resistance has been connected with the vane somewhat as shown in our device.

We are also aware that the m-ain easting Das been supported upon balls; but we are not aware that such balls have been heretofore arranged so that the shaf't A will not come in contact with the opening in the plante B.

'lhe lever c may pe pivoted to the main casting at any conven1ent point, and the brakeshoe should be provided with a spring behind it, substantially as shown in said patent to Anderson.

What we claim as new, am] desire t0 secure by Letters Patent, is-

HARRISON WOODMANSE. SAMUEL LEBKIOKER.
